This product is intended for installation in restricted access areas and is approved for connection
using 12 or 14 AWG copper conductors only. The installation must comply with all applicable
codes.
For central office installations, we recommend using a 6 AWG green ground wire with one end
connected to reliable earth. The other end of the wire should be crimped onto the double-hole
lug provided in the installation pack. The lug should be secured to the mating holes on the side
of the chassis with the two screws included in the accessory pack.
If you are installing a redundant power supply, you should attach appropriate-sized spade
terminals to the stripped ends of the ground and input wires.
